Evaporator Coil for Heat Pumps & Air Conditioners | HVAC Refrigeration No ratings yet.

Evaporator Coil for Heat Pumps & Air Conditioners – the evaporator is responsible for absorbing heat into the coils and the refrigerant. The evaporator is an essential component of vapor compression refrigeration. This is usually done as result of passing air or water over the evaporator coil where a heat exchange process takes place. Heat leaves […]

The Condenser for Air Conditioners and Heat Pumps| HVAC Refrigeration No ratings yet.

The Condenser for Air Conditioners and Heat Pumps The condenser coil receives the high pressure high temperature refrigerant vapor from the compressor and immediately begins to remove heat from the refrigerant vapor. As the refrigerant vapor makes its way through the condenser coil more and more heat is removed and the refrigerant vapor changes state […]

HVAC Centrifugal Compressors | HVAC Refrigeration No ratings yet.

HVAC Centrifugal Compressors – Centrifugal compressors are used in many applications including pipeline transport of natural gas along with many other related applications including vapor compression refrigeration. These compressors have different operating limitations than the reciprocating compressor, the scroll compressor, and the rotary compressor. They an operating range where it operates efficiently however outside of this […]

Rotary Compressors | Air Conditioning & Heating Systems No ratings yet.

Rotary Compressors – The rotary compressor used in HVAC applications for air conditioning and heating systems offer some of the most efficient air conditioner and heat pump systems one can find on the market. Despite the rotary compressor being a key component of an air source air conditioner or heat pump the efficiency offered by this […]

Refrigeration for HVAC | Air Conditioning and Heat Pumps No ratings yet.

Refrigeration for HVAC Air conditioners and heat pumps use the process of refrigeration to provide heating and cooling. What is the definition of the process of refrigeration? Refrigeration is the process of moving heat and depending on whether it is a heat pump or air conditioner and what mode it is in will depend where […]

Ammonia Chilled Water System | Commercial HVAC No ratings yet.

Ammonia Chilled Water System | Commercial HVAC This chilled water unit is a new ammonia chiller. This unit is also unique in that it has no compressor. Instead it uses the chemical properties of ammonia and heat from natural gas to condense the refrigerant which is ammonia. A chiller provides chilled water to a chilled […]

Vapor Compression Refrigeration | Refrigeration HVAC No ratings yet.

The process of refrigeration uses the vapor-compression refrigeration cycle to move heat from one place to another. In many HVAC air conditioning and heat pump applications the process of refrigeration or the vapor-compression cycle is what makes it work. This process, in the air conditioning mode, moves heat from inside the structure to the outside. […]

DX CRAC Unit Condensers | Critical Facility HVAC No ratings yet.

DX CRAC Unit Condensers | Critical Facility HVAC DX CRAC Unit Condensers | Critical Facility HVAC – Most data centers do not utilize HVAC DX (Direct Expansion) CRAC units or air conditioning but instead use chilled water systems to provide cooling for the data center. In smaller buildings such as remote telecom buildings DX air […]
